POE

POE(PowerOverEthernet)指的是在现有的以太网Cat.5布线基础架构不作任何改动的情况下,在为一些基于IP的终端(如IP电话机、无线局域网接入点AP、网络摄像机等)传输数据信号的同时,还能为此类设备提供直流供电的技术。POE技术能在确保现有结构化布线安全的同时保证现有网络的正常运作,最大限度地降低成本。

  • Power Over Ethernet

    December 2007, San Jose, California: It seems a long time ago. I walked into a big networking company to head their small Power over Ethernet (POE) applications team. Surprisingly, I hardly knew anything about POE prior to that day, having been a switching-power conversion engineer almost all my life. But it seemed a great opportunity to widen my horizons. As you can see, one notable outcome of that seemingly illogical career choice five years ago is the book you hold in your hands today. I hope this small body of work goes on to prove worthy of your expectations and also of all the effort that went into it. Because, behind the scenes, there is a rather interesting story to relate—about its backdrop, intertwined with a small slice of modern POE history, punctuated by a rather res- tive search for our roots and our true heroes, one that takes us back almost two centuries

  • Realtek交换机设计选型参考

    Realtek交换机设计选型参考设计交换机时候,确定了具体的芯片方案厂家以后,主要考虑以下几个方面:1:接口的情况:是要多少网口及其它延伸接口,采用什么封装形式;2:网口的带宽:是千兆还是百兆,或万兆;3:协议情况:管理型还是傻瓜式;4:POE供电:是否需要通过网口给设备供电;5:供电处理:内置电源模块还是外接供电,供电电压和电流要求;6:针对工业应用领域,有专门的工业级方案。设计的时候,需要根据具体的结构来实施布局走线,需要综合考虑,确保数据传输效率高运行稳!结合Realtek系列方案,做一些分析推荐选型。
